This is second step of making a moving text LED matrix…
The following circuit diagram is driver part-1 for 8 X 36 LED matrixes. You can build this circuit simply using a Vero board. The second part of driver circuit (Heart of the driver) is based on PIC16F84A microcontroller unit and I will present it with all details and assembly language program. If you have some knowledge about PIC microcontrollers, it may be useful for this project.
8 X 36 LED Matrix Driver Circuit Part-2 Will Be Soon...
